feat: promote studio theme to default, add favicon, deep-linkable lightbox

- Studio aesthetic now the default dark/light theme
- Removed MonochromToggle and 3-way theme cycle
- Light mode uses warm Studio-toned palette
- Added favicon (icon.png, apple-touch-icon, PWA icons)
- Lightbox URL sync: #photo-N hash for shareable photo links
- Browser back closes lightbox, shared links open directly
